Fork tube cap extension?

[Cajun]

I am starting to 'Fork Tube Cap Extension' pop up alot, more in racing scene, above are off a gsxr 1000, but know of them for sv650s etc etc.

And don't understand why you would want these. i understand it is to raise the forks thru the tubes more.

But why would you want to do this?

Handling dude, look at A strouds bike, always forks through the tripples as far as possible, BUT he is the only rider like that in NZ. They were highly reccomended in the USA on the GSXR for a while, but the sales have stopped, as the average road and bloody fast race riders, DO NOT use them at all any more.

They are actually brilliant for protecting the the top of your foks in case of big crash, I have used them for that purpose here a few times, as you know, I am a crasher, so thought I best protect other stuff, ha ha ha

But if the forks are through the triples as far as possible why would you put these on and make them even longer? Just to protect them?

Andrew;s style was just an example mate, the USA thought for a while that the bike handled best with even more than just the std length, hence the product is in the market!

get on the net, and check out the USA Suzuki bikes now, see if you can find one that is being raced using them now, Doubt you will!

When we fitted these to Strouds Ohlins suspended bike last year at Ruapuna he promptly broke the lap record with a 1 min 30 second lap and it was oh so close to doing a sub 1 min 30. He also won that same race. It was so stunning that Robbie came over after that race and asked " where in the hell did that come from?'' Stroudy being Stroudy he only asked us to fit them AFTER practice and qualifying, much to our concern of whether it would work or not.
I think this is more a Suzuki thing, it raises the c of g and affects fore and aft pitch and turn in. It affects a characteristic called ''polar moment of inertia''. You can tie yourself in knots trying to understand the theory but the bottom line is fit them and test them! We have fitted these to a K9 to test, even if they dont work as on the K7 it will as Shaun says give more crash protection damage.
Andrew was also impressed with them in that they become excellent anchor points for tiedown hooks!
We were also impressed in that Stroudys mechanic ( Rcktfish ) is so vertically challenged ( certainly not verbally ) that with the raised ride height it appeared as if Stroudys bike was making its own way to the grid!
I have seen photos of Mladins Ohlins suspended bike with their variation of these caps fitted, but whether they have continued with them I do not know.

With SV650s it may simply be that it allows them to ''tuck'' the steering head angle a little and still have wheel clearance to the radiator etc at full closed distance.

That's our Andy though, he is unique! I do not think he even knows how or where he got 7 children from

He knows exactly where he got his mechanic from though, a long lost pygmie tribe.

Easy powl, Rocktfish and me are similar in gutter level PS, and remember Diamonds come in small parcells!

Not the same, but: In the late 60's when Easy Rider came out everyone wanted to extend their forks. So the easy way was to add length by screwing in a long plug at the top. All was well as long as the plug length was not past the bottom clamp. This was realised soon as the ones who extended the screw in plug past the bottom clamp lost the forks and frontwheel while out riding...
